Classify the following atom as excited, ground state, or not possible.<br><br> 1s^2 2s^2 2p^6 3p^1
Luda [366]
According to Pauli's exclusion principle, the energy levels of the subshells should be arranged in an increasing manner. The energy of each subshell can be computed. In the sequence, the given subshells are arranged in a correct order. 30p allows 6 electrons at maximum so this configuration is considered as ground state

Good evidence for sodium water
luda_lava [24]

Answer: Understanding the timing and processes of synthesis and racemization of amino acids on asteroid parent bodies is crucial to showing how amino acids in living organisms on Earth grew to be predominantly left-handed. It has been postulated that racemization can occur rapidly depending on several factors, including the pH of the aqueous solution.Here, within the Tagish Lake carbonaceous chondrite, we perform a nanoscale geochemical analysis of a framboidal magnetite grain to show that the interlocking crystal structure formed within a sodium-rich, alkaline fluid environment. We study, in particular, on the discovery of Na-enriched subgrain boundaries and layers of Ca and Mg nanometer-scale surrounding individual framboids.
